Seizures and epilepsy of autoimmune origin: A long-term prospective study

Acute symptomatic seizures (ASS) are defined as clinical seizures occurring at the time of a systemic or brain insult. Seizures occurring in the context of an autoimmune disease, such as an autoimmune encephalitis, are considered autoimmune acute symptomatic seizures if signs or symptoms of immune activation are noted [1] The current International League Against Epilepsy (ILAE) terminology considers seizures in the context of autoimmune encephalitis at initial or relapsing presentations as acute symptomatic.
